Kylie explained that (- 4x +9)2 will result in a difference of squares because (-4x + 9)2 -(-4x)2 + (9)2 = 16x? +81. Which statement
best describes Kylie's explanation?
O Kylie is correct
O Kylie correctly understood that it is a difference of squares, but she did not determine the product correctly
O Kylie did not understand that this is a perfect square trinomial, and she did not determine the product correctly.
O Kylie determined the product correctly, but she did not understand that this is a perfect square trinomial.

The ratio pv to nrt is plotted against pressure for ch4 at 0°c and 200°c. why does the curve for 0°c drop below the horizontal line for an ideal gas whereas the curve for 200°c does not?

Determine the difference: 3.2 × 1010 – 1.1 × 1010. write your answer in scientific notation.

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
